Because of its height it looks a lot more top heavy than it is, the majority of the mass is low around seat level or below (the engine and heavier components are down there, a point mathematically calculated between your butt, back, seatbelt points and your hands on the steering wheel are where your mass is centered around, but you are a more dynamic mass than anything on the machine) . The cage has weight to it but while its probably around 50% of the height its not 50% of the mass of the vehicle. I'd GUESS maybe 5-10%.
All that to say the center of mass is low relative to what it appears to be because of the overall height of the vehicle.
To bad we don't have a 3-D CAD model that shows where the center of mass is on a factory 700
Also a XP1000 Highlighter edition is near as makes no difference the same overall height as a 4" lifted 700-4 with 28's so I would assume an XP 1000 is around the same height as a 700-4.
